Advice on a 625 CFM STREET DEMON CARBURETOR for 273 commando

I bought one a few years ago for the 360 in my '65 Barracuda. I love it. It was very nearly plug and play for my application. It starts right up every time and pulls and cruises perfectly. I have not one single complaint about the Street Demon 625.

Having said that, 625 CFM seems like maybe it's a bit much for a hot 273. When I was running my 273 I used an Edelbrock Thunder AVS 500cfm and it ran great. Others may disagree, but I was really happy about how easy it was to get installed and tuned. I always use an on-board A/F meter.

Cheers.
